Increasing electric vehicles usage, as a promising solution for environmental issues, might have unexpected implications, since it entails some changes in different sectors and scales in energy system. In this respect, this research aims at investigating the long-term impacts of electric vehicles deployment on Iran's energy system. Accordingly, Iran's energy system was analyzed by LEAP model in...

Executive Summary Biochar is an increasingly popular topic in environmental management due to its potential effects on several ecosystem functions. Specifically, biochar has been linked to significant reductions in greenhouse gas emissions, including nitrous oxide, carbon dioxide and methane when used as a soil amendment. It has also been suggested as a long term mechanism to sequester carbon i...

Claimed human-caused warming of the Earth to dangerous and unprecedented levels by human-related emissions of carbon dioxide is contradicted mainly by a non-correlation of carbon dioxide levels with warming. Details are given of misleading proxy temperature reconstructions, as well as of misleading proxy atmospheric carbon dioxide concentrations. Evidence is presented to show that trepidation a...

The oxidation of luciferin catalyzed by sea pansy luciferase results in the emission of light. Molecular oxygen is required and carbon dioxide is produced. When the reaction occurs in the presence of H(2) (18)O, both of the oxygens of the carbon dioxide are labeled. One of the oxygens arises from the nonenzymic exchange of the ketone group of the substrate; the other oxygen is incorporated duri...

Two process models are used to convert carbon dioxide into methanol. These processes have been extended and improved using Aspen Plus simulator software. Both processes are found in the CO2 correction system. In this machine, the desired synthesis gas is produced in a flexible configuration. At the same time, the conversion of CO2 to hydrogen via a copper-based catalyst ha...

With the rapid economic development of the Xinjiang Uygur Autonomous Region, the area’s transport sector has witnessed significant growth, which in turn has led to a large increase in carbon dioxide emissions. As such, calculating of the carbon footprint of Xinjiang’s transportation sector and probing the driving factors of carbon dioxide emissions are of great significance to the region’s ener...

One of the major factors, contributing to the emission of greenhouse gases in the environment is generation of pollutant gases in municipal landfills. As for the design and building of a gas collecting system, it is necessary to properly estimate the amount and type of the landfill emissions. By means of LandGEM model, this study predicts the amount and type of the landfill gases, produced for ...

Background and purpose: Hospital wastes pose a serious public health problem. This is primarily caused by the way individual components of the waste is handled. One acceptable method for managing the medical waste is incineration but uncontrolled incinerators can cause emission of pollutants to atmosphere. The objective of this study was to evaluate pollutants emission from hospital waste ...
